  1. Shown are the normalized (test/reference) mean ratios together with the corresponding standard deviations (σ), p-values and numbers of analyzable shRNA expression constructs (n) for each dilution factor. The p-values reflect significance of the differences between mean ratios obtained from the undiluted subpool-0 and the indicated dilution factors. For n < 3, no standard deviation or p-value could be determined.
